Vanguard Mining completes Redonda drill program to 511m

Executive Summary

• Vanguard Mining Corp. has completed its Q4 2025 drill program at the 100%-owned Redonda copper-molybdenum project in British Columbia, drilling a total of 511 metres.
• Assay results for the 2025 program are currently pending; no laboratory analytical results have been received at the time of this release.
• The company highlights historical drilling data from 1979 and 2023, noting intervals of up to 142.6 metres grading 0.279% copper and 0.0281% molybdenum, while emphasizing that these are historical results not verified as current resources.

Key Details

• Drilling Completion: Total depth of 511 metres drilled during the Q4 2025 program.
• Contractor & Equipment: Program executed by Paradigm Drilling Ltd. using a Boyles T-75 hydraulic, track-mounted diamond drill with NQ tooling.
• Assay Status: All core has been logged and submitted to ALS Canada Ltd. for analysis. Results are pending. Visual observations of alteration and sulphide mineralization were noted but are not indicative of grades or economic significance.
• Historical Context (1979): Teck Resources Ltd. completed nine NQ-diameter diamond drill holes totalling 1,681 metres.
• Recent Historical Drilling (2023): Five drill holes totalling 799.81 metres were completed.
• Historical Assay Highlights:
  • Drilling returned intervals of up to 142.6 metres (467.8 feet) grading 0.279% copper and 0.0281% molybdenum.
  • Surface sampling yielded near-surface intervals ranging from 3.1 metres to 48 metres grading 0.529% copper equivalent.
  • Note: These results are historical in nature and should not be relied upon as an indication of current mineral resources or reserves.
• Geophysical Survey: Targets were guided by a late-2024 airborne geophysical survey (conducted by Precision GeoSurveys Inc.) integrating total magnetic intensity, gradient magnetics, and radiometrics.
  • Identified a northeast-southwest-trending fault system with right-lateral offset.
  • Identified circular magnetic lows interpreted as potential intrusive centres.
  • Radiometric potassium anomalies defined arcuate potassic-alteration zones.
• Community Engagement: Priority placed on collaboration with the Klahoose First Nation, including local labour, training, and use of Klahoose-affiliated service providers. Consultation with the Homalko First Nation has concluded, with a permit for additional drill sites issued.
• Project Location: Redonda project comprises nine mineral claims (2,746.46 hectares) located ~40 km northeast of Campbell River, B.C., within the Coast Suture zone.

Notable Quotes

• David Greenway, CEO: "The 2025 drill program was designed to test targets beyond the limits of historical drilling and to improve our understanding of the geological framework at Redonda. Drilling has been completed as planned, and all core has been logged and submitted for analysis. While we have observed alteration and sulphide mineralization consistent with the known Redonda system, visual observations alone are not indicative of mineralization grades or economic significance. Assay results are required to determine the presence, extent and continuity of mineralization. Results from this program, together with historical data and previous drilling, will be used to guide future exploration planning at the project."
